solve for indicated variable

Question

P=aw+9 solve for (w)

 

Bx-y=-2y solve for (y) 

 

 

Answer 1

P=aw+9

 

=>aw=P-9 .... subtracting 9 from both sides

=>w =(P-9)/a .... dividing both sides by a.

Hence solution for w is (P-9)/a

 

Bx-y=-2y

 

=>Bx-y+2y=0 .... adding 2y to both sides

=>Bx+y=0 ...

=> y = -Bx ... subtracting Bx from both sides

 

Hence solution for y is -Bx
